Marina police said they arrested Michael Erickson, 64, of Aptos, in the Marina Walmart parking lot Friday morning after he placed a solicitation contact ad on Craigslist and then arranged to meet and sell prescription drugs, specifically a packaged Viagra-type substance, to plainclothes officers. Erickson, an unverified, self-proclaimed practicing medical physician in the San Jose area, was booked into Monterey County Jail, police said.

This investigation continues. The Marina Police Department asks anyone with information about previous contacts with Erickson to call the Marina Police Department Investigations Bureau at 831-884-1210 or use the department's website at marinapolice.com.
